i have the rx-v390 for five years now, i'm only using the front l-r speakers and it's working fine, but i'm thinking of upgrading with a sub woofer for extra oomph. is there a way to get through this when there's no specified output for the sub? can i use the center output?i have the rx-v390 for five years now, i'm only using the front l-r speakers and it's working fine, but i'm thinking of upgrading with a sub woofer for extra oomph. is there a way to get through this when there's no specified output for the sub? can i use the center output?

just connect your subwoofer mono RCA to your amp sub single out rca connector. you do not need to megre all those 4terminals into one. in fact internal circuit of those 4rca are merging inside to one since the sub uses only a single amp. 4inputs was meant for sources with multiple sub out

Since you're using a standard mini jack to double RCA cable, it's safe to assume you'll be sending line level signal into your reciever, so i think any of these audio inputs will do: AUX, CD, DVD, MD, TV.

Also try the inputs on the front of the unit (i guess they are meant to be used with a video camera or similar but they are designed for line level signals so it should be ok if you decide to use them).

Anyway, keep the source signal at a moderate
level when you test any of the inputs and raise it to a suitable level after you're sure it is coming thru well.

Normally, the AUX input is suitable for any AUXilliary signal source that puts out a line level signal, but if it is already being used, you may use other free inputs.

If you use TAPE or PHONO inputs, you should keep the signal level from the source a bit lower since these inputs will amplify the signal a bit more (especially the phono input which works with signals that are lower in level than the line signal).

You can connect PS3 video via HDMI to receiver and from receiver via HDMI to TV. But RX-V365 doesn't support HDMI audio, so you have to connect audio separately via SPDIF digital cable. I think PS3 uses optical SPDIF, so you will need optical cable. If you can't find cheaps optical cables in your shop, you can try byuing from ebay ($1-5 max.)

If you disconnect the Speakers and then turn back on and get the same fault then it is the Amplifier.

If it stays on OK then you need to turn off again and connect one Speaker at a time (turning off again between each one) until you find the fault Speaker.

If it is the Amplifier thats faulty then it could be a simple repair that would involve replacing some Capacitors but you would need a Soldering Iron and the knowledge how to de-solder and re-solder components to a PCB.

Does your receiver have any kind of line level audio output? AUX OUT, LINE OUT or similar? If so, you might be able to send that a subwoofer. Most standalone subwoofers have their own crossover and level controls built in, so you can make adjustments there.

Does it display something on LCD? Maybe you have connected speakers with wrong impendance and the receiver is overheating.Check the impedance of speakers, it should be at least 6 ohm. Also check the receiver manual if it has settings for impendace (6 or 8 ohm).

I have the same setup. Are you going out of the subwoofer output of the reciever? (it's purple.) then into the LFE jack of the subwoofer (also purple.) That's the only connection you need besides power. If you have those right, try using your cable for something else to make sure the cable is good. Is the indicator of the subwoofer green? Mine comes on with the reciever. Good luck!

Modern home-theater components monitor themselves electronically for potentially dangerous malfunctions such as damaged internal parts. When a unit's microprocessor senses a problem, it will typically shut down so that no further damage -- or potentially dangerous disasters like fire! -- occurs. Your receiver is identifying something upon turn-on and shutting down as a result. My guess is that you're going to need service for your Yamaha. There's likely no fix that you're going to find. You need a professional service technician.
